    Server-side Request Forgery (SSRF)

    ip-address is an A library for parsing IPv4 and IPv6 IP addresses in node and the browser.

    Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) in the isInSubnet function. An attacker can bypass network trust-boundary checks by appending a CIDR suffix with a shorter prefix (such as /0) to an internal address, causing classification methods to incorrectly treat internal addresses as external. This allows requests to internal resources to be permitted when they should be blocked.

    Note: This is only exploitable if an application accepts a bare address string with a CIDR suffix and passes it directly to the constructor before classification, such as in allow/deny fields, webhook targets, or proxy destinations taken as plain hosts rather than parsed from a URL.

    How to fix Server-side Request Forgery (SSRF)?

    Upgrade ip-address to version 10.2.2 or higher.

    Server-side Request Forgery (SSRF)

    ip-address is an A library for parsing IPv4 and IPv6 IP addresses in node and the browser.

    Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) through improper handling of IPv4 addresses with leading zeros in the Address4. An attacker can bypass network trust-boundary checks by submitting specially crafted IP addresses that are interpreted differently by the library and the underlying network resolver, potentially allowing unauthorized access to internal resources.

    How to fix Server-side Request Forgery (SSRF)?

    Upgrade ip-address to version 10.3.1 or higher.
